Domino Printer A420i

Ink and Make-up Cartridge Replacement

WARNING: Do not smoke or allow naked flames (or other sources of ignition) in the vicinity of any inks or solvents as this is highly dangerous.

Messages ‘Add Ink Cartridge’ or ‘Add Make-up Cartridge’ will appear when the ink or make-up cartridges need replacing, and the amber alert will illuminate. Enter the relevant cartridge codes when prompted.

(1) Remove the old cartridge by rotating the ink cartridge anti-clockwise and the make-up cartridge clockwise to free it before lifting it away.

Note: This mechanism ensures that the cartridges cannot be fitted onto the wrong manifold.

(2) Insert a 6mm hex key into the top of the new ink cartridge and twist to break the sealing tab. Remove the sealing tab.

(3) Push the cartridge onto the i-Tech Module or make-up reservoir manifold. Ensure the label is facing forwards.

If the make-up cartridge is not replaced, the make-up reservoir will empty and the ink viscosity will eventually go outside its operating limits. Also, head flushing will not be carried out when the printer is shut down and ink may be deposited on the print head components. The printer can still be used but head faults may occur.

Air filter replacement is recommended after every 2000 hours of operation but may need to be replaced sooner depending on the operating environment.

A new air filter can be ordered through BuyDomino which can be found on the Domino Printing website.

(2) The air filter is located in a slot to the side of A320i/A420i printers or at the rear (under electronics cabinet) on A520i printers. As a user replaceable part it is coloured yellow.

(3) Remove the air filter by holding the yellow exposed part of the filter and pulling it gently out of the filter housing.
